摘要
人工合成包裹体目前主要以石英包裹体为主,而作为地球化学和石油地质学中重点研究的碳酸盐岩流体包裹体鲜有合成方面的报道。本文利用高温高压釜在100MPa,350℃下促使方解石裂隙愈合合成碳酸盐岩流体包裹体(NaCl-H2O),模拟了包裹体的形成,并利用激光拉曼光谱及显微测温技术对合成包裹体的成分、均一温度、盐度等参数进行了定量分析,验证了合成包裹体的准确性。
The most of synthetic inclusions are quartz inclusions, carbonate inclusions as one of the most important fluid inclusion in geochemistry and petrology are seldom be synthesized. In this study, using the high temperature and pressure vessel , the carbonate synthetic fluid inclusions （HEO-NaCl system） were formed under pressure 100MPa and at the temperature 350℃. It also qualitatively analyzed the composition of synthetic inclusion with laser Roman microscopy and tested the homogenization temperature and the ice-melting temperature of synthetic inclusions with freezing-heating stage. The salinity and density of synthetic fluid inclusions were calculated with thermodynamics methods and confirmed feasibility of fluid inclusions＇quantitative analysis. It is indicated that quantitatively synthetic technology of fluid inclusions can supplemented each other very well.
